Gustav Pielstick, Augsburg, Germany, assignorto 'MaschinenfabrikAugsburg-Number: A. G., Augsburg, Germany, a corporation of GermanyInGermany April 22, 1929 albums. (01. 121-194) This invention relates tointernal combustion power engines, and more particularly to engineframes orhousings. The primary object of the invention is\ the 5provision of an engine frame or housing which is built up of -a number.of separate wrought iron or steel pieces integrally united. together bywelding or the like to provide a frame which is strong and yet which iscomparatively light in weight. p

Furtherobjects and advantages of the invention will be apparent in thefollowingdescription and from the accompanying drawings in which Fig. 1is a vertical section of an engine according to the invention;

Fig. 2 is a vertical section through an engine frame or housing, takenalong the line 1-l of Fig. 4; p

Fig. ,3 is a side elevation, the right half of the view being shown insection along the line of 2,-2 of Fig. 4; and

Fig. 4 is a top plan'vlew, shown in section.

at the right, along the line 33 of Fig. 2.

In accordance with prior constructions of internal combustion enginehousings or frames, these frames have been generally made of cast ironor light metal, and have been either cast as an integral part, or madeup of assembled castings,-usually screwed together. The housings ,of thelight metal cast constructions are.

of light weight, but are not sufllciently rigid, and the cast ironconstructions are quite heavy. .In accordance with the presentinvention, however, the housing is constructed of wrought iron or steelprofile pieces and connecting parts or plates welded together to providea unitary structure of light weight and great rigidity."

As shown in Fig. 1 of the drawings the engine 40 frame or housing is ofthe type used in vertical internal combustion engines, the frame servingas a support for a series of cylinders A, held at the top of the framepreferably by means of vertical through bolts B that project downthroughthe frame or housing and interconnect the frame with the lowerremovablecrank bearing and support the cylinders in place. The frame or housingof the present invention comprises separate upright standards or profilepieces 0 a, each of which is preferably a wrought'iron or steel barwhich is milled from a single'piece of metal and provided with alongitudinally extending passage through which a tension rod may extend.If desired recesses a maybe pro- I 'vided in the laterally extendingfaces of the upright standards. These standards are connected togetherby wrought iron or steel plates b, c and d which are welded at b, c andd respectively. 'The plates b and d are preferably rather narrow stripsextending laterally 'between adjacent standards, while the plate 0extends continuously past the various standards, as shown in Fig. 3.Plate 0 is provided with circular openings 0 through which the pistonrod of the adjacent cylinder extends. The cross strips or plates b whichextend down as shown at b along theinner sides of the standards are alsowelded at their lower ends at b to the top portions of the upwardlyextending flangedprojections e of the base plate e. Each of the platesd, which may be of T-section as shown, has a pair of spaced downwardlyextending tongues 11 at each end, which are welded to the opposite sidesof the standard ends. The upper ends of the standards, where they extendthroughthe plates cl, are of reduced circular section as indicated at dfor a vertical height equal to the thickness ofthe plate d. Sidestifiening members f are provided along the lower sides of the housing,being constructed of suitably bent 39 wrought iron, welded to theprofile pieces a at f and tothe base plate e at f. Vertically extendingplates g extend between the plates c and b to provide lateralreinforcement between the profile pieces a, the plates y beingwelded tothe 35 plates b and e at g andi'to the profile pieces a at a. Theseplatesg and the "additional lateral bracing means provided between theuprights by the plates b and d rigidly interconnect the opposedstandards together, while the longitudinal plate 0 and the side andbottom plates 1 and c interconnect all of the standards longitudinally.As all the connecting plates which are welded to the standards arearranged to conduct forces horizontally between standards, it will beapparent that the vertical forces acting through the uprights are notcarried through the welds or through the connecting plates, which are,therefore, normally without substantial strain. The slide 71. for thecross-head is screwed to the rear side of the profile pieces a by bolts2',

each slide being a separate plate extending between adjacent profilepieces.

While the for-tn of apparatus herein described constitutes apreferred-embodiment of the invcntion, it is to be understood that theinvention is not limited to this precise form of apparatus, and thatchanges may be made therein without departing from the scope of theinvention which is defined in the appended claims.
